Tools

| Tool | Status | Description | |---|---|---| | lookup_word | Confirmed working | Look up a term, get Thai translations per subject field. | | search_suggestions | Best-effort | Autocomplete suggestions for a partial term. | | list_domains | Best-effort | List the 40 subject fields and their book_ids. |

lookup_word is built against a real captured response and tested against it — reliable.

search_suggestions and list_domains hit real endpoints (searchAutoComplete.php, function_All.php) confirmed via captured requests, but I haven't seen a live response from either yet, so the parser is defensive: it tries JSON, then HTML lists, then plain text, and returns whatever it finds under a format field so you can see what shape the data actually came back in. If either tool returns something unhelpful, open DevTools → Network on the site, trigger that action, copy the Response tab content, and I can tighten the parser in a minute.

Step-by-step install

1. Clone this repository

git clone https://github.com/chakkritt/orst-coined-word-mcp.git
cd orst-coined-word-mcp

2. Install Node.js dependencies

Make sure you have Node.js installed (this project targets the active LTS version).

npm install

This installs the runtime dependencies needed to call the Royal Society website's internal endpoints and return the results as MCP tool responses.

3. (Optional) Test the server by hand

You can quickly verify the server starts without errors:

node index.js

The process should stay running and wait for MCP messages. Stop it with Ctrl+C.

4. Register the MCP server with Claude Code

From inside the project directory, run:

claude mcp add orst-coined-word -- node "$(pwd)/index.js"

This adds the server to your Claude Code user config so it is available in every project.

If you prefer to register it only for the current project, or you are not using the claude CLI, add it manually to one of these files instead:

• User-level config: ~/.claude.json
• Project-level config: .mcp.json in the repo root

Example .mcp.json / ~/.claude.json entry:

{
  "mcpServers": {
    "orst-coined-word": {
      "command": "node",
      "args": ["/absolute/path/to/orst-coined-word-mcp/index.js"]
    }
  }
}

Replace /absolute/path/to/orst-coined-word-mcp/index.js with the actual absolute path.

5. Restart Claude Code and verify

Restart Claude Code, or run /mcp inside Claude Code to reconnect to the MCP server.

After reconnecting, Claude Code should show three new tools:

• lookup_word
• search_suggestions
• list_domains

You can test by asking:

> Look up the Thai coined term for "computer" using orst-coined-word.

Claude Code Skill

This repo also includes SKILL.md, a reusable Claude Code skill for Thai academic writing. Drop it into your skills directory (e.g. ~/.claude/skills/thai-coined-term-lookup/) and Claude Code will use it automatically when you are writing Thai academic text that includes English technical terms.

The skill guides Claude to:

• Look up official Royal Society coined terms (ศัพท์บัญญัติ) versus transliterated loan words.
• Choose the right term for formal theses, dissertations, journal papers, and research proposals.
• Present results with a short table and a one-line recommendation.

See [SKILL.md](./SKILL.md) for the full prompt and behavior.

Example usage

After installing and registering the server, ask Claude Code:

> Look up the Thai coined term for "computer" using orst-coined-word.

Claude Code calls lookup_word with {"word": "computer"}. A typical result includes multiple subject-field entries, each showing the Thai translation(s) endorsed by that field:

| Subject field | Thai translation(s) | |---|---| | วิทยาศาสตร์ | คอมพิวเตอร์, คณิตกรณ์ | | คณิตศาสตร์ | คอมพิวเตอร์, คณิตกรณ์ | | วนศาสตร์ | คอมพิวเตอร์, คณิตกรณ์ |

You can then choose the appropriate form for your document. In a Thai academic thesis, for instance, you might write คณิตกรณ์ on first use with the English term in parentheses, then use คอมพิวเตอร์ consistently thereafter if your committee prefers the more common transliterated form.

Notes / limitations

• The site uses a PHP session cookie (PHPSESSID). This server bootstraps one session

on first use and reuses it for the life of the process — if the server runs for a very long time and the session expires server-side, restart it.

• book_id defaults to 0 (search across all subject fields). Once list_domains is

confirmed working, you can pass a specific book_id to lookup_word to restrict to one field.

• This is an unofficial integration against a government site's internal endpoints, not

a documented public API — endpoint behavior could change without notice.

• All source data and terminology definitions remain the intellectual property of the

Royal Society of Thailand (ราชบัณฑิตยสภา).
